ABSTRACT
Positioning for postero-anterior wrist projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_89a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
The patient is seated alongside the table, with the affected side nearest to the table.
The elbow joint is flexed to 90 degrees and the arm is abducted, such that the anterior aspect of the forearm and the palm of the hand rest on the image receptor.
If the patient’s mobility allows, the shoulder joint should be at the same height as the forearm.
The wrist joint is placed central to the image receptor and adjusted to include the lower part of the radius and ulna and the proximal two-thirds of the metacarpals.
The fingers are flexed slightly to bring the anterior aspect of the wrist in contact with the image receptor.
The wrist joint is adjusted to ensure that the radial and ulnar styloid processes are equidistant from the image receptor.
The forearm is immobilised using a sandbag.
